OSCAR ALLEN, OF MOUNT MORRIS, NEW YORK.

IMPROVEMENT IN SPOKE-POLISHING MACHINES.

Specification forming part of Letters Patent No. 1 95,555, datedSeptember 25, 1877; application filed August 10, 1877.

To all whom it may-concern Be it known that I, OSOAR ALLEN, of MountMorris, in the county of Livingston, and in the Stateof New York, haveinvented certain new and useful Improvements in Machine for FinishingSpokes; and do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

The nature of my invention consists in the construction and arrangementof a machine for finishing spokes after being turned in a lathe, as willbe hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in which-Figure 1 is a front elevation of my machine. Fig. 2 is a plan view, andFig. 3 a transverse vertical section, of the same. Figs. 4, 5, and 6 aredetails. Fig. 7 is a perspective view of the complete machine.

A represents the base upon which the machine is erected. The frame ofthe machine consists of two end pieces, B B, connected by twolongitudinal bars, B B. O is a countershaft, having its bearings in theend pieces B B, and provided on' each end with a pulley, D, around whichis placed a quartz-belt, E, said belt passing around another pulley, Dso arranged as to make the top of the belt horizontal. The belt alsopasses around a pulley, D, at the bottom of the end piece. This latterpulley D is mounted on a stud projecting from a slide, G, placed in avertical slot in the end pieces B. On top of the two slides or slidingboxes G G is placed a bar, G through the center of which is passed avertical screw, G having its bearings in the bars B B and upon saidscrew is a nut, G which, by being screwed down, causes the bar G topress on the boxes G G, forcing the same downward to tighten the beltsfEE.

H represents a right and left hand screwshaft, which has its hearings inthe side pieces B B, and has also a center bearing in an arm, B,projecting from the top bar B, as shown.

Motion is communicated from the engine to the counter-shaft G, from thisshaft to a short shaft, a, and from this latter to the screwshaft H, allby suitable belts and pulleys.

In front of the screw H is a rod, I, placed in suitable bearings, andmovable laterally therein. On one end of this rod is placed a tube orsleeve, I, passing through the bear ings on that side of the center armB and also movable in said bearings.

On each side of this center arm the mechanism is precisely the same,that on one side being attached to the red I, while that on the otherside is attached to the sleeve I.

On the outer end of the rod I or sleeve I is secured an arm, J, throughthe front end of which is passed a centering-screw, K. A suitabledistance inward from this arm are fastened two arms, L L, by means ofset-screws b b. Between these arms is placed the pulley M, to which thefacer N is attached, and through the center of said facer and pulley ispassed a shaft, 0, with a crotch, d, at its inner end, to receive thetenon of the spoke, the other end of the spoke being held by thecentering-screw K.

The shaft of the crotch d may be drawn out and in, as required, to suitlong or short spokes, and the shaft held by a pin through the facer.

The facer N is provided with removable corner-pieces h h, fastened withscrews i, so as to be altered for finishing any size or style of spoke.

Between the arms L L on the rod 1 or sleeve I is a sleeve, L forming twoflanges, ff, on its rear side, between which are pivoted two arms, L Lwith a spring, is, so arranged between them as to throw their outer endsapart.

The outer ends of these arms are so constructed as to form,when closedtogether,a nut around the screw-shaft H. L is a latch for holding saidarms closed.

The pulley M is, by a belt, connected with a pulley, M, feathered on thescrew-shaft H, the feather-groove in said shaft extending the entirelength thereof. and said pulley M held in a fork in one of the flangesflThe arm L is extended forward, forming a handle for holding the spokedown against the polishing-belt, and below said arm is another arm, Lalso hinged on the rod I or the sleeve 1'. From this arm L projects alug, m, against which a regulating set -screw, n, through the arm L,bears, to regulate the depth at which the spoke is to be depressed. Theend of the arm L at the commencement of the outward movement, passesthrough an inclined slot, at, in a track, 0, and is held against therear side thereof by the tension of a cord, 1), attached to the arm L orL, and passing to the other end of the machine over a pulley, and with aweight, P. suspended from it. At the outer end of the track 0 is anincline, y, over which said arm L rides, and when it passes the same itis thrown forward to the front of the track, raising the spoke from thequartz-belt.

It will be seen that there are two sets of holders for spokes, withtheir appropriate mechanisms operating from the center outward towardboth ends, the movement of the two sets being simultaneous, andcoinciding exactly.

The nuts being thrown in connection with the screw-shaft, said screwmoves the two sets outward, at the same time rotating the spokes, whichare held against the quartz-belts for being finished. At the same timeas the arm L is thrown in front of the track 0, as above described, thefacer N strikes on an adjustable rest, R, whereby the facer is thrownover the corner, and is dropped on the flat part of the spoke. As thismovement is completed, or, in other words, simultaneously therewith, thelatch L strikes against a stop, S, and is released from the arms L L,which thus open by the action of the spring it between them, and theweight P at once returns the holder to the center of the machine, wherethe spoke is removed and another inserted.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a machine for finishing spokes, two sets of holders, operatedsimultaneously in opposite directions by a right and left handscrew-shaft, substantially as herein set forth.

2. The combination of two sets of spokeholders, a right and left handscrew-shaft for operating the samein opposite directions, and twoendless rotating quartzbelts, substantially as and for the purposesherein set forth.

3. In a machine for finishing spokes, the combination of two endlessrotating quartzbelts, two tightening-pulleys mounted on studs projectingfrom vertically movable slides, a single pressure-bar, and a stationarycenter-screw with nut, whereby the two belts are adjusted simultaneouslyto the same tension, as herein set forth.

4. The combination of the two sets of spokeholders, thelaterally-movable rod, and the laterally-movable sleeve on said rod, asand for the purposes herein set forth.

5. The combination of the facer N with removable corner-pieces h h,pulley M, and shaft e, with crotch d, substantially as herein set forth.

6. The combination, with the spoke-holder, of the sleeve L with flangesff, the arms L L with interposed spring it, screw H, latch L and stop S,substantially as and for the purposes herein set forth.

7. The combination, with the spoke-holder, of the arm L with lug m, theset-screw n, track 0, with slot :10 and incline y, and the cord 1), withweight P, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 2d day of July, 1877.

OSCAR ALLEN. [L. 8.]
